# Add a new comment to a card — Trello

Botize method — `trello.add_comment` (action).

Add a new comment to a Trello card identified by its card ID.

This is an action: it runs as a step of a task. Several can be chained.

## Fields you set

The field's internal name, its type and the values it accepts. These fields accept `{{...}}` tags from earlier steps.

- `id_card` *(string)* — Card Id
- `comment` *(string)* — Comment for the Card

## Output variables

Data this step makes available. Reference them in later steps with the double-brace tag.

- `{{_status}}` *(text)* — _status
